This PA can be easily configured for high-power appli- cations with high power-added efficiency while operat- ing over the 2.4-2.5 GHz frequency band. It can operate at both 3.3V and 5V VCC, and typically pro- vides 38 dB gain with 25% power-added efficiency @ POUT = 28 dBm for 802.11g at 5V. SST12CP33 has excellent linearity, typically 25 dBm at 3% EVM with 54 Mbps 802.11g operation at 5V while meeting 802.11g spectrum mask at 28 dBm and 21 dBm at 3% EVM at 3.3V bias. SST12CP33 also has a single-ended power detector which lowers the users’ cost for power control. The power amplifier IC also features easy board-level usage along with high-speed power-up/-down control. SST12CP33 is offered in 16-contact UQFN package. See Figure 3-1 for pin assignments and Table 3-1 for pin descriptions. SST12CP33 2.4 GHz WLAN Power Amplifier, 802.11b/g/n/256 QAM |
